This here is the all-new Mercedes-Benz S-Class-based Brabus SV12 R Biturbo 800. With 800 hp (597 kW) and 1,047 lb-ft (1,420 Nm) on tap, the R800 sets a new milestone in the luxury segment, while dwarfing the S65 AMG in the process.

This luxo-barge-on-steroids uses the same V12 engine that originally came with the BRABUS E V12. That means that the displacement has been increased from 5.5 to 6.3 liters (336 to 385 cui), by using a special crankshaft with longer stroke, larger pistons and corresponding larger bore.

A new air intake is also used, alongside high-performance manifolds and water-to-air intercoolers.

While the engine is capable of delivering a peak torque of 1,047 lb-ft (1,420 Nm) at 2,100 rpm, for technical reasons (as in not to tear apart the transmission) it has been limited to 'just' 811 lb-ft or 1,100 Nm. Even so, the five-speed automatic transmission had to be thoroughly strengthened.

BRABUS claims that the SV12 R Biturbo 800 is also the world's fastest luxury sedan with an electronically limited(!) top speed of 217 mph (350 km/h). Breaking the 62 mph (100 km/h) "barrier" in just 3.9 seconds is no small feat either.

Naturally, the suspension, brakes and aerodynamics have been heavily modified, so that your average oligarch can safely wring every ounce of performance out of this beast.

The tour de force continues in the cabin, where countless combinations of leather or Alcantara and exclusive wood trim sets are available. The iBusiness multimedia system deserves a special note, as it's for the very first time that various Apple components have been fully integrated into the vehicle electronics of the Mercedes S-Class.

There's no information on the price yet, but surely it will match all the other specs. And who cares? If you really want the fastest opulence there is, you'll surely find a way to "has it..."
